I use public WiFi in cafes and libraries all the time, but I would never use a public computer there. I bought an HP Netbook, and a Logitec keyboard for my phone, and both of those allow me to use my own equipment. Neither of them cost much money, so I can't see the point in using a public computer. The only time I have done it is to assess a library printer, and you need to scan a library membership card to do that.
How safe is this?
If person X used a laptop that held some of their bitcoins over public WIFI is there any chance at all that somebody could for example steal their wallet.dat &/or see what their wallet password is.
Nobody else has access to person Xs laptop ever but is there a chance at all that somebody could access their laptop via the public WIFI if theyre online using it at the same time?
